Subject: linux-next: build failure after merge of the regulator tree

Hi all,

After merging the regulator tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/msm/edp/edp_ctrl.c: In function 'edp_regulator_enable':
drivers/gpu/drm/msm/edp/edp_ctrl.c:335:2: error: implicit declaration of function 'regulator_set_optimum_mode' [-Werror=implicit-function-declaration]
  ret = regulator_set_optimum_mode(ctrl->vdda_vreg, VDDA_UA_ON_LOAD);
  ^

Caused by commits e39ce48f5362 ("regulator: Rename
regulator_set_optimum_mode") and ae6e808f1574 ("regulator: Drop
temporary regulator_set_optimum_mode wrapper") interacting with commit
ab5b0107ccf3 ("drm/msm: Initial add eDP support in msm drm driver
(v5)") from Linus' tree (in v4.0-rc1) tree.

There was another use of regulator_set_optimum_mode() in
drivers/phy/phy-qcom-ufs.c (introduced by commit adaafaa393ef ("phy:
qcom-ufs: add support for QUALCOMM Technologies UFS PHY drivers") also
from v4.0-rc1) which I also fixed in the patch below.

grep is your friend ...

This patch should be applied to your tree as it is based off v4.0-rc1
already.
